### Required Reading
|
|
|
|
In order to exploit the SAFE_MODE firmware of our system, we need to inject an exploited WiFi profile.
|
|
|
|
We can do this using an existing exploit, BannerBomb3.
|
|
|
|
To accomplish this, we use your system's encryption key (movable.sed) to build a DSiWare backup that exploits the system in order to inject the exploited WiFi profile into your connections list.
|
|
|
|
Once the WiFi profile has been injected, we will use SAFE_MODE, which is a recovery feature present on all 3DS consoles, to activate the exploited WiFi profile.
|
|
|
|
These instructions work on USA, Europe, Japan, and Korea region consoles as indicated by the letters U, E, J, or K after the system version.
|
|
|
|
If your (Right/Left Shoulder), (D-Pad Up), or (A) buttons do not work, you will need to follow [an alternate branch of Seedminer](bannerbomb3). For assistance with this matter, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

### What You Need
|
|
|
|
* Your `movable.sed` file from completing [Seedminer](seedminer)
|
|
* The latest release of [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/latest)
|
|
* The latest release of [boot9strap](https://github.com/SciresM/boot9strap/releases/download/1.4/boot9strap-1.4.zip)
|
|
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest)

#### Section I - Prep Work
|
|
|
|
1. If your device is powered on, power off your device
|
|
1. Open [unSAFE_MODE Exploit Injector](https://3ds.nhnarwhal.com/3dstools/unsafemode.php) on your computer
|
|
1. Upload your movable.sed using the "Choose File" option
|
|
1. Click "Build and Download"
|
|
+ This will download an exploit DSiWare called `F00D43D5.bin` and a SAFE_MODE exploit data file called `usm.bin` inside of a zip archive (`unSAFE_MODE.zip`)
|
|
1. Insert your SD card into your computer
|
|
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of your SD card
|
|
+ The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
|
|
1. Create a folder named `boot9strap` on the root of your SD card
|
|
1. Copy `boot9strap.firm` and `boot9strap.firm.sha` from the boot9strap `.zip` to the `/boot9strap/` folder on your SD card
|
|
1. Copy `SafeB9SInstaller.bin` from the SafeB9SInstaller `.zip` to the root of your SD card
|
|
1. Copy `usm.bin` from `unSAFE_MODE.zip` to the root of your SD card
|
|
+ ![]({{ "/images/screenshots/usm-root-layout.png" | absolute_url }})
|
|
{: .notice--info}
|
|
|
|
1. Navigate to `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare` on your SD card
|
|
+ The `<ID0>` will be the same one that you used in [Seedminer](seedminer)
|
|
+ The `<ID1>` is a 32 character long folder inside of the `<ID0>`
|
|
+ If `Nintendo DSiWare` does not exist, create it inside of the `<ID1>`
|
|
1. If there are any existing DSiWare backup files (`<8-character-id>.bin`) in this folder, move them to your PC
|
|
+ This will leave you with an empty Nintendo DSiWare folder. Moving the files to your PC ensures you don't delete any intentional backups
|
|
1. Copy the `F00D43D5.bin` file from `unSAFE_MODE.zip` to the `Nintendo DSiWare` folder
|
|

#### Section II - BannerBomb3
|
|
|
|
1. Reinsert your SD card into your device
|
|
1. Power on your device
|
|
1. Launch System Settings on your device
|
|
1. Navigate to `Data Management` -> `DSiWare`
|
|
1. Click on the SD Card section
|
|
+ Your device should show a menu with some text
|
|
1. Select "Inject haxx"
|
|
+ Your device will automatically power off
|
|
|
|
#### Section III - unSAFE_MODE
|
|
|
|
1. With your device still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), then press (Power)
|
|
+ Keep holding the buttons until the device boots into Safe Mode
|
|
1. Press "OK" to accept the update
|
|
+ There is no update. This is part of the exploit
|
|
1. Press "I accept" to accept the terms and conditions
|
|
1. The update will eventually fail, with the error code `003-1099`. This is intended behaviour
|
|
1. When asked "Would you like to configure Internet settings?", select "Yes"
|
|
1. On the following menu, navigate to `Connection 1` -> `Change Settings` -> `Next Page (right arrow)` -> `Proxy Settings` -> `Detailed Setup`
|
|
+ This is a [visual representation](https://uwuu.ca/images/safemode_highlighted.png)
|
|
1. If the exploit was successful, your device will have booted into SafeB9SInstaller
|
|
|
|
#### Section IV - Installing boot9strap
|
|
|
|
1. When prompted, input the key combo given on the top screen to install boot9strap
|
|
+ If the top screen is blank, power off your device and re-do Section III
|
|
1. Once it is complete, press (A) to reboot your device
|
|
|
|
#### Section V - Configuring Luma3DS
|
|
|
|
1. Your device should have rebooted into the Luma3DS configuration menu
|
|
+ You can access the Luma3DS configuration menu at any time by powering off, holding SELECT, then powering on your device while still holding SELECT
|
|
+ If you get a black screen, [follow this troubleshooting guide](troubleshooting#boot-related-issues-on-modded-devices)
|
|
1. Use the (A) button and the D-Pad to turn on the following:
|
|
+ **"Show NAND or user string in System Settings"**
|
|
1. Press (Start) to save and reboot
|
|
|
|
At this point, your console will boot to Luma3DS by default as long as the SD card is inserted.
|
|
+ Luma3DS does not look any different from the normal HOME Menu. If your console has booted into the HOME Menu, it is running custom firmware.
|
|
+ On the next page, you will copy Luma3DS to internal memory so that you can boot without an SD card.
|
|
|
|
#### Section VI - Restoring WiFi Configuration Profiles
|
|
|
|
1. Launch System Settings on your device
